CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 245,770, dated August 16, 1881.

Application filed J une 1G, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOHN H. BLANCHARD, a citizen ofthe United States of America, residing at Boston, in the county of' Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Oar-Gouplings; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled 1o in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference m arked thereon, which form a part of this specification.

I5 This invention relates to car-couplings; and it consists in the construction and arrangement of parts as hereinafter more fully described and claimed.

In the annexed drawings, which fully illus zo trate the invention, Figure l is a plan view. Figs. 2 and 3 are longitudinal sections. Fig. 4L is an end view of car, showing a transverse section through the draw-head, taken on the line .t x of Fig. l. Fig. 5 is a view of the unz 5 der side of draw-head and draw-bar. Fig. 6 is a perspective view of draw-bar. Fig. 7 represents a side view and plan of coupling hook or link. A

Likelettersof reference indicate correspond- 3o ing parts in the several views.

The draw-head A, which is constructed of cast-iron or other suitable material, is provided on its under surface with a central lon gitudinal slot or groove, a, forthe reception of the 3 5 wrought-iron draw-bar B, a recess or depression, a', having beveled sides, being formed at the inner end of the slot a, into which iits a correspondingly-formed shoulder, b, on the end of the detachable draw-bar. This enlarged- 4o head or shoulder fitting within the recess a serves to assist the pins b b in holding the draw-bar in place. By this construction the objectionable effects of casting the draw-head around the wrought-iron tongue or bar, which tends to chill the latter and renders it lnore liable to break, are obviated, and the parts may also be more easily repaired or replaced 'when necessary.

In the upper part of each draw-head on one 5o side is a recess, (l, open at the top, in which is pivoted acoupling hook or link, D. The hooked end of this link is beveled upward and out-ward to correspond with the face ofa catch, E, on the oppositel draw-head, which catch is beveled or inclined upward and inward, so that the end of the link D will pass readily over it and bring its eye or slot d into engagement with the catch Ein coupling two adjoiningcars. At the lower portion of the beveled end of the link D is a projection, d', which fits into a depression at 6o the back of the catch E and renders the coupling more secure. The beveled catch E on each draw-head is located at the front end or mouth of a recess, C', which adjoins the recess O, and, like the latter, is open at the top. This recess O is beveled or inclined backward, from below upward, at` its rear end, to accommodate the movements of the hooked link D. The inclined rear portion of the recess O is slotted for the recept-ion of a lever, F, which is pivoted in lugs 7o or bearings c' at the top of the incline, and lies under the beveled end of the hook or link D when the cars are coupled.

At the upper or rear end of ,the recess C in each d raw-head are lugs or bearings c, in which is pivoted a lever, Gr, the shorter end of which bears upon the top of the link D at its rear end, while the longer or rear end of the lever Gr is connected by a chain, g, with a lever-handle, H, att-ached to the end ot' the car I. The lever- 8o handle H is also connected by a chain,f, with the lever F, and by a chain or cord, t', with the top of the car.

It will be seen that by operating the leverhandle H either directly from the side of the car or through the chain t' from the top of the car the chains fg will actuate the levers F Gr to simultaneously raise both links, one being raised by the lever F pushing the beveled end ot the link upward and the other by the lever 9o G bearing down upon the rear end of the link.

The recesses C C', in which the links are engaged, are beveled or iiared outward at the sides, so as to afford the links sufficient lateral play. These links are preferably constructed of wrought-iron, and are pivoted in their respective recesses by pins e @,so as to be capable of being readily removed when desired.

A stop-pin, e', may be placed in each recess U, if desired, to limit the movement of the link. roo

In order to facilitate coupling with cars provided with the Ordinary links, each draw-head is provided with a cavity, h, for the reception of said links, suitable openings, h', being provided in each for the passage of the ordinary coupling-pin.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the draw-head A, having slot or groove a and recess al' on its lower surface, of the detachable draw-bar B, having enlarged head or shoulder b, and secured by pins b b', substantially as and for the purpose specified.

2. The combination, with the draw-heads A A, havingrecesses C C', lugs c c', and beveled catch E, of the coupling hooks or links D, having slots d, and beveled ends provided with projections d', yand adapted to be operated by the levers F G, substantially as and for the purpose set forth.

3. The combination of the draw-heads A,

having open-top recesses C C', beveled catchmay be simultaneously operated from the top or side of either car, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
